This will require a lot of manipulating - it will only be worth it in my opinion if you have a few hundreds of these.
With the ASR plugins you will have to take several steps, but before that you should filter all titles mentioning 'contributing artists' and standardize the label for it.
It can be ft. ft feat. feat. featuring & with vs vs. etc...
I actually have more than a couple hundred of those files.
I understand that this kind of process won't be as quick as a one-click after boroda74 taught me to formalize my separator under the same symbol which is ";" (semicolon). so I took the initiative to Search and Replace "feat.", "featuring", etc. so they'd all be the same "ft."
After you have found all tracks with all these variables, use general search and replace (not the ASR plugin) to replace the variables step by step by a uniform unique character (example: #).
Then use the ASR plugins to split the title tag in two separate tags, using the # as a splitter. The contributing artist could be stored in an empty field such as TEMP (you can create that yourself.
Then use the copy tag plugin to add the newly isolated contributing artist to the end of the original one, separated by ; (see the bottom S&R features for that)
Quite some work - but possible...
You got me confuse here. The format I use for tracks with a featured artist is this:
Title (ft. Featured Artist)
Note that the featured artist is enclosed in parenthesis with the word "ft." to offset it.
I want to copy the names of the featured artist in the artist tag, but I also want to retain the name of the featured artist in the title, if it's possible.
I hope I explained clearly.
Thanks.
